Point taken. I probably shouldn't have sent this one. This is something 
we're doing in our internal trees to make sure we catch warnings at 
pre-submission stage. Please ignore warnings too frequently and I'm 
getting tired of fixing all of them.

Would be nice if there was some consistency to gcc's warnings, but 
that's not something I see happening ever.
